Correction to QER

No non-compliance against PM10 Outcome Measurable Criteria

Review: “PM10 dust levels collected from the HiVol PM10 sampler located at the visitors viewing area (Figure 44 - same location as the HiVol sampler), will be sampled over a 24hour period every six days as per AS, 3580.9.3:2003 standards. Data will demonstrate compliance with NEPM 1998 criteria of <50 micrograms/m3 per 24 hour period with <5 days exceedances per year.”

Terramin still conducted investigation as to why

Hydrostor A-CAES System Basics

Terramin Zinc Mine A-CAES System

Benefits for Australia

Fossil Plant Replacement

• Repurpose decommissioned thermal plants and defer remediation costs

• Re-use of existing interconnection and infrastructure• Synchronous generation for reliability, without emissions

Transmission Deferral

• Non-wires alternatives to defer grid network investment• Alleviates grid congestion during peak periods• Locatable reliable power for critical areas and infrastructure

Renewable Integration

• Provide dispatchable, base loaded renewables• Optimize solar/wind project economics through time-shifting • Reduce curtailment

Mines / Large Industrial

• Ability to eliminate fuel costs & logistics (off-grid)• Improve reliability and reduce electricity grid charges (on-grid)• Re-use legacy mining infrastructure
